Product Description
Inogadzirwa pamwero wakakura kunyanya kugadzirwa kwemapolymers. MuEuropean Union, ine E-nhamba E1520 yekushandiswa kwechikafu. Zvekuzora uye pharmacology, iyo nhamba ndeye E490. Propylene glycol inowanikwawo mupropylene glycol alginate, inozivikanwa seE405. Propylene glycol musanganiswa unova GRAS (unowanzo zivikanwa sewakachengeteka) neUS Food and Drug Administration pasi pe21 CFR x184.1666, uye zvakare inotenderwa neFDA kune mamwe mashandisirwo seasina kunanga chikafu chinowedzera. Propylene glycol inotenderwa uye inoshandiswa semotokari yemusoro, yemuromo, uye imwe intravenous mishonga yekugadzirira muUS uye muEurope.

Application
| Inowanzoshandiswa sechinhu chinobatsira mumishonga yakawanda yekugadzirira kuwedzera kugadzikana uye kugadzikana kwemushonga. |
Mukugadzirwa kwemishonga, MEA inonyanya kushandiswa kubhafa kana kugadzirira emulsions. MEA inogona kushandiswa se pH regulator mune zvekuzora.
Iyo injectable sclerosant senzira yekurapa yesymptomatic hemorrhoids. 2–5 ml ye ethanolamine oleate inogona kubaiwa mucosa iri pamusoro pemahemorrhoids kuti ikonzere maronda uye mucosal fixation nokudaro kudzivirira hemorrhoids kuburuka kunze kweanorasika.
Icho chinhu chinosanganisa mukuchenesa mvura yemagetsi emotokari.
Advantage
Mushonga wacho dzimwe nguva unonzi (alpha) α-propylene glycol kuti usiyanise kubva kune isomer propane-1,3-diol, inozivikanwa se (beta) β-propylene glycol. Propylene glycol ndiyo chiral. Maitiro ekutengesa anowanzo shandisa racemate. Iyo S-isomer inogadzirwa ne biotechnological nzira.
1,2-Propanediol chinhu chakakosha mbishi ye polyester isina unsaturated, epoxy resin, polyurethane resin, plasticizer, uye surfactant. Mari inoshandiswa munharaunda iyi inokwana 45% yehuwandu hwekushandiswa kwepropylene glycol. Inoshandiswa zvakanyanya mumucheka wepamusoro uye mapurasitiki akasimbiswa. 1,2-propanediol ine viscosity yakanaka uye hygroscopicity, uye inoshandiswa zvakanyanya sehygroscopic agent, antifreeze agent, lubricant uye solvent mumaindasitiri ezvekudya, emishonga uye zvekuzora. Muchikafu chekudya, 1,2-propanediol inopindirana nemafuta acids kuti iite propylene glycol fatty acid esters, iyo inonyanya kushandiswa sekudya emulsifiers; 1,2-propanediol inonyungudutsa yakanakisa yemwaka uye pigment. Nekuda kwekuderera kwayo muchetura, inoshandiswa sechinhu chinonyungudutsa chezvinonhuwira uye ruvara rwechikafu muindasitiri yechikafu. 1,,2-Propanediol inowanzoshandiswa sechinhu chinonyungudutsa, chinopfavisa uye chinobatsira mukugadzirwa kwemafuta akasiyana-siyana nemafuta muindasitiri yemishonga, uye sechinhu chinonyungudutsa chekubatanidza maajenti, kuchengetedza, mafuta, mavitamini, penicillin, nezvimwewo mumishonga yemishonga. industry . Nekuti propylene glycol ine yakanaka miscibility nemhando dzakasiyana siyana inonhuhwirira, inoshandiswawo sechinhu chinonyungudutsa uye chinopfavisa chezvizoro. 1,2-Propanediol inoshandiswawo sefodya moisturizer, antifungal agent, lubricant yekugadzira chikafu uye solvent yekudya kumaka ingi. Aqueous solutions ye1,2-propanediol inoshanda antifreeze agents. Inoshandiswawo sefodya wetting agent, antifungal agent, kuchengetedza michero yekuibva, antifreeze uye inotakura kupisa, nezvimwe.
